Introduction: The treatment with growth hormone (GH) plays an essential role in the Turner syndrome (TS) management. This study evaluated its efficacy in improving adult height (AH) and metabolic parameters.Material and methods: We retrospectively analysed auxological, biochemical, genetic and pharmacological parameters of 56 girls with confirmed TS. They were categorised according to their karyotype as X monosomy (62%), isochromosome (17%), X mosaicism ...

Introduction: Zinc homeostasis is involved in numerous physiological and pathological conditions, ranging from type 1 and type 2 diabetes to memory impairment and cancer, and is determined by at least 28 genes, including 24 SLC (Solute Carrier) family members and 4 MTs (Metallothioneins). To explore the potential role of zinc homeostasis in MetS (metabolic syndrome) and IR (insulin resistance), we investigated 28...

Introduction: The prevalence of palpable thyroid nodules in Graves’ disease (GD) is approximately 15%. Cytopathologic interpretation in GD is challenging due to frequent cytomorphologic changes, namely after radioactive iodine (RAI) therapy. Some of the few published studies regarding fine-needle aspiration (FNA) in patients with GD, suggest an increased risk of malignancy of thyroid nodules arising in GD patients. However, the results are inconsistent, and there is no co...

Introduction: Breast cancer is the second most common neoplasm in women. Hormonal replacement therapy and combined hormonal contraception are established extrinsic hormonal risk factors for breast cancer. Therefore, the increase in the prevalence of infertility and the use of assisted conception techniques have raised questions regarding the potential risk of hormone-dependent neoplasms. We report the case of a woman diagnosed with bilateral metastasized breast cancer soon aft...

Background: Multiple endocrine neoplasia type 1 (MEN1) is an inherited syndrome, characterized by primary MEN1 tumors: parathyroid, pancreatic and pituitary. We describe the case of a patient with MEN1 syndrome, initially presented with a gastric neuroendocrine tumor (NET).Case presentation: A 33-year-old male patient, initially treated for perforated gastric ulcer, presented 7 years later with dyspepsia, diarrhea and weight loss. Abdominal CT scan revea...

Background: Vitamin D deficiency has been proposed to play a role in development and course of Graves’ disease (GD). Muscle weakness and fatigue are shared features of GD and vitamin D deficiency. We aimed to investigate whether vitamin D supplementation would improve restoration of muscle performance and thyroid-related quality of life (QoL) in GD.Methods: In a double-blinded clinical trial, hyperthyroid patients with a first time diagnosis of GD w...

Background: Aldosterone-producing adenomas (APA) are a major cause of primary aldosteronism. Somatic mutations explain the excess aldosterone production in the majority of patients with APA with mutations in the potassium channel KCNJ5 the most prevalent. In contrast, mechanisms driving cell proliferation are largely unresolved.Objective: To identify genes that modulate cell growth in APAs.Methods: Quantitative transcripto...

Background: Tumour microenvironment (TME) can comprise >50% of the tumour mass and includes non-tumour cells like immune cells and fibroblasts, as well as extracellular matrix, signaling molecules, and blood and lymph vessels. In recent years, TME has begun to be considered both a prognostic tool and a therapeutic target. While the existence of TME is well accepted and described in numerous cancers, little is known about the TME of pituitary neuroendocrine tumours (PitNETs...

Background: Risk of cardiovascular disease (CVD) and mortality is increased in Graves’ disease (GD) even years after initial diagnosis and treatment. The mechanisms are incompletely understood. Vitamin D insufficiency is associated with an increased risk of CVD and has been reported to occur frequently in GD. Pulse wave velocity (PWV) and blood pressure (BP) are important predictors of CVD. We performed a clinical trial, testing whether vitamin D supplementation affects P...
